An embodiment of the first aspect of the present application provides a display panel 100, as shown in fig. 1 and fig. 2, the display panel 100 includes a substrate 1, a plurality of pixel units 2, and a microlens layer 5, where the plurality of pixel units 2 are distributed in a matrix on one side of the substrate 1; the microlens layer 5 is located on a side of the plurality of pixel units 2 away from the substrate 1, the microlens layer 5 includes a plurality of microlens units 51 corresponding to the plurality of pixel units 2, and adjacent microlens units 51 are abutted along a long side direction of the display panel 100, and/or adjacent microlens units 51 are abutted along a short side direction perpendicular to the long side direction.
In the embodiment of the present application, as shown in fig. 2, a plurality of pixel units 2 are distributed on one side of a substrate 1 in a matrix. The microlens layer 5 includes a plurality of microlens units 51. Further, since the adjacent microlens units 51 are in contact with each other in the longitudinal direction and the short direction of the display panel 100, there is no gap between the adjacent microlens units 51 in the longitudinal direction and the short direction, that is, the plurality of microlens units 51 are in close contact with each other in the longitudinal direction and the short direction. Therefore, after the light at the boundary of the adjacent pixel units 2 enters the microlens layer 5, the light is not emitted through the gap between the microlens units 51, and the light is emitted after being refracted and reflected by the upper microlens unit 51, so that the probability of interference between the light of the adjacent pixel units 2 can be reduced, the probability of optical crosstalk generated in the display panel 100 is reduced, and the display effect of the display panel 100 is improved. In addition, in the display panel 100 provided in the embodiment of the present application, the positions of the plurality of microlens units 51 and the positions of the plurality of pixel units 2 are arranged in a one-to-one correspondence manner, so that the light in each pixel unit 2 can be emitted through the corresponding microlens unit 51, and the microlens layer 5 has a higher light transmittance, thereby improving the light transmittance of the display panel 100 and further improving the display effect of the display panel 100.
Further, the pixel units 2 include a plurality of red pixel units, a plurality of blue pixel units, and a plurality of green pixel units distributed in an array. Therefore, the microlens units 51 are closely attached to each other, so that the probability of optical crosstalk between adjacent pixel units 2 of different colors can be reduced, and the display effect of the display panel 100 can be improved.
Further, the substrate 1 may be a rigid substrate, such as a glass substrate or the like. The substrate 1 may also be a flexible substrate, such as a polyimide substrate, and the like, which is not limited in the present application. The method for forming the microlens layer 5 on the substrate 1 includes, but is not limited to, a photolithography thermal reflow method, a transfer method, and the like.
In some embodiments, the microlens unit 51 includes cylindrical lenses, axes of the cylindrical lenses are parallel to the short side direction, and a plurality of the cylindrical lenses are arranged in at least one row along the long side direction.
In the embodiment of the present application, as shown in fig. 7 and 8, the axial direction of the lenticular lens is parallel to the short side direction of the display panel 100. Each of the microlens units 51 may include one lenticular lens, and the lenticular lenses of the plurality of microlens units 51 may be arranged in at least one row along the long side direction of the display panel 100. Wherein, the row number of the plurality of cylindrical lenses can be determined according to the length of the cylindrical lenses along the axial direction. Specifically, the length of the lenticular lens in the axial direction may be substantially equal to the width of the display panel 100, and thus, the lenticular lenses in the plurality of lenticular units 51 may be arranged in a row in the long side direction of the display panel 100.
In the embodiment of the present application, the plurality of pixel units 2 may include a plurality of rows of pixel units 2 extending along the width direction of the display panel 100, and each cylindrical lens is disposed corresponding to at least one row of pixel units 2. Because the cylindrical lens array has the advantages of mature manufacturing process, convenience in large-size processing and the like, in the embodiment of the application, the microlens unit 51 comprises the cylindrical lens, the realization of large-size of the microlens unit 51 and the microlens layer 5 is facilitated, the microlens layer 5 can meet the processing requirement of the large-size display panel 100, and the process difficulty and the production cost of the microlens layer 5 and the display panel 100 are reduced.
